About this Mod

This datapack makes the nether coordinates 1:1 with the overworld. Encourage using the overworld to travel! It overrides the default the_nether dimension with one that is exactly the same, but with the coordinates scaled 1:1 with the overworld.

I haven't tested it with any other datapacks. I suspect it works on versions earlier than this one, but I haven't tested.

Frequently Asked Questions

1:1 Nether server crashes on startup – what to do?

Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.5). You can switch loaders with one click in the panel.

Is 1:1 Nether compatible with datapack and fabric and forge and neoforge and quilt?

1:1 Nether officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.5, 1.21.4, 1.21.3. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with 1:1 Nether – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if 1:1 Nether consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
